wm3|away>: it would probably be more interesting and useful if you added in drills for things like 'you have an array in the variable current_users. Write some code that will pull out all users that are over 18. Each user is a hash, and has an :age key'

to get people to start using things like select, find, etc. rather than looking at a printout and hard-coding some keys & indices :)
